it is very stupid? (Realforce silencing)
« on: Thu, 17 August 2017, 12:04:41 »
Hello, gentlemen. I try to build theories on the subject of how to make a realforce more silence.

Conventional methods are known:
   - lubing
   - Purple sliders (Hypersperes etc.)

Yes they work, but not solve the main problem - housing.



Realforce case as if designed to amplify the noise. There are too much empty space and different cavities that create all sorts of revibrations.
I reflected on what to score this place some good sound dempering materials. And here I had a strange idea, which came from the artisans casting. What if to fill the empty space with the molding silicone?

There are many questions: how to do it proper?
Will it cause any damage to the pcb?
Dielectric properties of silicone?
How about heat removing?
Is it possible to spray on the pcb product, which is used for better removal of the silicone?(don't know how is called)

Do you think this could work or is it stupid?

You could try sound dampening foam, although I don't think it would make a big difference...
At least it doesn't do much for pc's

well, silicone is a semiconductor, which means it can act as either a conductor or insulator just depends on what it interacts with. it is probably a bad idea bc i believe silicone will become a conductor when heat is applied and this could cause all kinds of circuit malfunctions

How about resting the board on a strip on that foam?  You could fill the case with shelf liner or felt.

I have not tried it, but someone suggested modeling clay that does not dry hard.

Personally, I use rubber waffle material and felt, flat in sheets or rolled into cylinders.
In 1979 Jimmy Carter warned of a spiritual crisis that he identified as toxic to American ideals: "Too many of us now tend to worship self-indulgence and consumption. Human identity is no longer defined by what one does, but by what one owns. But we’ve discovered that owning things and consuming things does not satisfy our longing for meaning. You see every extreme position defended to the last vote, almost to the last breath by one unyielding group or another. We see a balanced and fair approach that demands sacrifice, a little sacrifice from everyone, abandoned like an orphan without support and without friends. We have lost our way … because we have exalted “a mistaken idea of freedom"; our self-indulgence had led us to assert every right as absolute, every form of compromise or regulation as inimical to freedom, and to elevate the very avatar of self-absorption to the highest office in the land.” (ie Reagan!) Carter warned the nation against following the “path that leads to fragmentation and self-interest”, for “down that road lies a mistaken idea of freedom, the right to grasp for ourselves some advantage over others”.

Plumbers putty would probably be better than modeling clay.  Not sure long term how it would interact with the case plastic though.

Look up neoprene foam sheets. They come in many thicknesses. You can use thin sheets for the shallower areas then thicker sheets for the deeper areas. I put a piece between my PCB and plate on one of my 60%. You will notice a different if you put it between the case and PCB.

Felion modded the case of his Wooting One with electrical tape on the ridges and under stabilisers, and automotive bitumen sheet in the hollows to add weight and stability.
I don't think he posted about it here, but he did post a gallery on SweClockers in Swedish. Don't worry about the language - the pictures speak for themselves.

Bitumen sheets are used in automobiles just for cancelling vibrations.
I have seen other weight-mods on the forum in the past, with lead. Some custom keyboard models come with a large piece of brass in the bottom - which I suppose is for the same reason.

Yes, thank you. Very uncompromising solution. Something like this I had in mind))

I have had the same idea and believed that to be fine - only because fine models are moulded with it. It should not be exothermic either.
"robo" on Deskthority (I don't know if he is here) ruined his keyboard using silicone caulk... because it released chemicals while curing that ate away at the PCB.
If you would pour RTV inside an empty plastic cavity, removed it, cleaned it and then replaced it, I think you should be safe. Especially if you used food-grade silicone that is supposed not to leak anything after it has cured.
